Screen swap, CF-29 Compatability

I know that some devices use different parts for different versions of the same model... that being said,
I have an MK1 touchscreen (the touchscreen is failing intermittently), and have a line on a working touchscreen. Are all the LCDs and touch screens compatible from one mark to another? The donor screen is from an sbc, and the screen size is the same (so far as I know, they are both 13.3")
The other thing is that the replacement screen's bezel is a little torn up (and my current bezel is nice); what is your opinion on cutting the rubber gasket and actually swapping the touch glass itself??? I have some industrial double sided foam tape (really nasty stuff, I got it from my buddy who does outdoor advertising and uses it to hang ads that are exposed directly to the elements). I also realize that the touch screen itself will be quite fragile once out of the frame.

TIA!

 

I have moved MK2 to Mk4 with no issues.

Well, I'm gonna say, with a descriptive title, and 40 views, no one has jumped out and said "no", so i feel a little better about trying.

And I was thinking of trying to use some butyl as a new gasket (the nasty black silicone like substance they use for car windshields... dunno.

 

I did the Mark 3 to Mark 4 no issues. I feel from my limited experience that the thickness of the gasket??? is critical. Too thick and it will not play nice with the touch screen.Does your Mark I MB look like this? The white plug is disconnected out of alignment. The black one comes next. In the second image you are looking down past the modem with the keyboard PCB with antenna connections in the upper left. Top of PCMCIA cage on the left.

 

I personally would not use the butyl. If you ever need to take it apart again, you will regret using butyl. That stuff can be a real pain to clean up. I would search various types of tape at home improvement stores and auto parts to find the correct thickness.

 

Too be honest, I'm not totally sure. I had cracked open the lid ad case several months ago to see if it was just a loose connection causing the touch screen issues. I know I looked up how to do it, and found pictures (here and in the manual) and I remember nothing seemed different (# of pins, locations of connections, etc) between my own and the info I had found.

My touch screen wont align properly ( see here) and now, once it's docked in the car for a few hours, the touch screen stops working till i get it in the house. i roll with the a/c all day, but I think it may be heat/sun related. It's happened twice in the last week, so, i'm looking to fixit.

And the gasket thickness is a good point.

And, thanks for the pics, Gork!

 

I got used to no touch screen with the LAQ but it was supposed to work so I have been trying to find the right donor for a while. I got one but the inverter was shot which was no issue other than I fed the little wires through the holes twice. The touchscreen is alright though. Plays pretty good with Ubuntu. In fact the 1.6 's don't have the complications that the 1.4's have re: package drivers.

But that's another story.

Good luck and consider the real deal(gasket) from Panny if you are going all the way to the bezel. I believe it is critical. Don't ask me how I know or I might have to send you the results.
FWIW

So you've tried to cut the glass off the gasket? How did that work out for you? how'dyadoit? what went wrong?

i don't recall the exact thickness of the gasket, but from memory, it's quite close to the thickness of that nasty tape i was talking about (I also used that tape to mount my gps and board).

i'll look into a replacement gasket, although, i had priced up the glass from panny or heartland (don't remember which) and it was ~$699 shipped, so I'm gonna prepare myself for some astronomical number for the rubber.

 

No I didn't have enough sense to attempt to keep the gasket in place. Part stayed on the screen and part on the bezel. Scraped it all off.....used one kind of DS tape...too thin. Used another....too thick......didn't get the glass inserted within the bezel correctly, screwed the back on and snapped the glass. (twice) There....all my dirty laundry in one place.
If you place an order to panny pick me up some thermal pads.

Edit: Take pictures, go slow and go clean. The pictures are for you when putting it back together. Also keep an eye out for another donor. Just in case. If you are successful post the pictures. Good luck. J

 

4 things:
What is "laq"?
checck ebay, there is a dude selling the touch glass w/bezel and control board for about $165.
Which thermal pads (processor/video heat sinks)(don't hold your breath, I probably won't be willing to spend that much, sorry)(I'll still check)?
& Thanks!

 

I have had no issues swapping out tscreens from any model CF-29 to any model CF-29.... I think I've covered them all in the past 4 years...

Perhaps TBTech29 can chime in to make sure... You can take him to the bank.

<He might like that!>

 

Cable wise, the LCDS will work. Now there are minor differences in the LCDS between the models but I am not sure of exactly what.

 

There you have it... Worth his weight in gold! Thanks!

 

Well that is great news!

I don't plan on swapping the lcd, just the touch glass, so kudos to the bearer of good news, thanks!

 

Sorry I didnt read the whole thing lol. The touchscreen between the marks are the same.

You can remove the glass from the adhesive if your careful.

Go to Walmart or home depot, and get a set of dental picks.

Use the curved(rounded) one to get between the adhesive and the glass, and take it slow you should be able to pull it off without marring the foam pad.

 

and what, the adhesive should still be good?

TIA!

 

Thats how I have done it before

 

Watch the subtle sense of humour. (sic) There is no smiley with a tongue in cheek. IOW I was kidding.

Good news is you have the real deal now from folks that know what they're talking about.

and your welcome.

awesome, cool, and thanks again, to all!

I'll report back, I have all kinds of shizzle coming in the mail to play with soon...

 

First off, someone get tbtech29 a friggin cookie! the dental pick worked like a charm. I just wish I had shoved some coal up my wazoo prior to attempting the task. I would have had some nice diamonds to sell. I was as careful as I could be, but tbtech29, how easy is it to cut/break a trace with the pick?

Now, on to the bad news.
I got crap stuck all over the gasket. which solvent would be best to clean that up without damaging the adhesive? Denatured alchohol? %91 isopropal? Anything I would know to use would just remove the adhesive/melt the gasket. i was thinking some really thin double sided tape (the clear stuff) might be in order?
Also, my cursor is going to the bottom of the screen again. I have a feeling it's the crud stuck to the gasket (same symptom was cured by the toothpick trick before).

I took pictures. I'll post some more stuff later, for now, I'm off to see the wizard (it's 0030).

And BTW, don't ever try to remove a crimp IPX connector from really thin coax, and try to reuse it on rg316. I tried to take a picture of the center conductor on a penny, but it just looked like a booger on Lincoln's face.

 

ripped it back apart:
I re-removed the glass and cleaned it thoroughly (the old one too). I then fired up the TB with the display disassembled but hooked up. My old glass worked for about 30 seconds and then went dead, and the new glass still only moved the pointer across the bottom of the screen. I"m thinking it might be the cables? I have already tried both ts boards as well.

I've got those other two 29's coming in soon, I'll try my displays on one of those, to make sure it's not my mobo.
